The death of Pope Francis has been mourned around the world. His pontificate was one of humility and a deep and unwavering commitment to put the very poorest in society first. Francis was a very human Pope but also an adept statesman. He discovered very early on in his reign that his role required top level diplomacy as well as spiritual leadership and one of the most famous moments came in 2014 when the Head of the Roman Catholic Church welcomed the Supreme Governor of the Church of England, Elizabeth II, to Rome. As the death of Pope Francis is mourned, we look back at a moment of history.
